This invention'relates to water jackets for vacuum tubes and pertains more particularly to de-.

mountable water jackets which may be quicklyadjusted for the insertion or removal, of a vac- =5 uum tube. x

It is an object ofmy invention to provide a jacket structure whereby a vacuum tubean'ode having an annularshoulder or ring thereon; may

be quickly clamped intoposi'tion without the aid i=1!) of complicated tools.

ln accordance withmyinvention the'end of the water-jacketadjacent the metal to glassseal of a vacuum tube orelectron discharge device is provided with a plurality of posts serving to'sup- 16 port a screw threaded ring adapted for engagement with a holding collar which serves to retain the vacuum tube in proper position relative to the jacket. The threaded ring may be a completejcircle or composed of segments, each of which is'supported. by a post. The spacing between these posts is sufficiently wide to permit the operator to adjust the split ring elements cooperating with the retaining collar and adapted to hold the tube in position. If desired and as I shown in the drawingthe spacing between the posts may be made wide enough to permit of the complete removal or insertion of the split ring I elements without necessitating the removal of the vacuum tube from the water jacket. Alternatively the split ring'may be hinged at one side,

in which event the wide spacing between the posts leaves the sides of the split ring freely exposed so that the ring may be opened and moved out of position preparatory to the removal of the vacuum tube from the jacket.

The above mentioned and further objects and advantages of my invention and the manneryof I attaining them will be more fully explained in,

the following description taken in conjunction with the accompanying drawing.

'In the drawing, v Fig. 1 is a side elevation view partly in section of a jacket structure embodying my invention.

Fig. 2 is an end view taken along section line 2-2 of Fig. 1.

.of an electromidischarge device (not shown) which the" jacket holds in position and then pass out through thezwater ou'tletnipple 4; The right .hand endjof the-jacketl, as illustrated in Fig. l,

has attached thereto by; screws is two posts 6 and- 1, which in turnasupport asthreaded ring 8 preferably formed integrally therewith. The ring E'Jha's screw threaded-' therethr'ough a pressure collar '9 having an inwardly slo-ping-annularportion It! terminatingin a pressure face i l which 10 engages'g'with the two halves or sections 12- and 1301: a split ring indicatedgenerally by reference numeral, i4. This split *ring has a recess 15 in the'surface thereof adjacent the pressure face i I of collar 8 with which the pressure face engages,

with the result that the two halves of the ring are held together and are-prevented from spreading apart during the tightening of thencollar. The

other sideofthesplit ring is chamfered slightly at l6 so as to permit free movement thereof to-. 20 ward the main body of the jacket I, the portion of the jacket adjacentto the ring l4 being provvided with'a recess or seat l'i adapted to receive a shoulder or ring fixed to or. integral with'the' tubular metal devicei Reference numeral 19 indicates knurled handles attached .to the halves l2 and. 13 of split ring, I4, by means of which these halves may be inserted anode of an electron discharge gr,

and removed as desired. 1

' 3 In operation the collar 9 is unscrewed far I enough to permit the removal of the tjwo'halves l2 and I3 of split ring. I4. .The tubular anode I of'an electron discharge device is thrust through the opening inj the' collar, 9 and moved into the 35 opening in jacket l'farenough to bring the ring orshoulder carried by the anode into the recess or seat I! of the jacket, whichlse'atit is adapted substantially to fill. At the same time gaskets may be provided for one or both sides of the ring or shoulder of the'anode so as to insure a water tight joint with the seat l1.

The two halves or sections l2 and it of split ring 14 are then placed in position between the' pressure face ll of the collar 9 and the opposite 5 face of'the anode shoulder, and the collar 9 is screwed into position so as to force the split ring l4 tightly against the shoulder-of the discharge device. I The resulting pressure clampsthe anodef shoulder tightlyin the seat I! and forms a water tight joint. I I I As shown on the drawing the spacing between theposts 6 and 1 is made wide enough to'permit the direct removal of the sections l2 and I3 of split ring 14 .and the insertion thereof without 15x5 I special tools, this wide opening also serving to of the split ring shown in Figs. 1 and 2, the

spacing between the posts 6 and I need not be great enough to permit the complete removal of the hinged ring from the structure by passage thereof between the posts, since the removalot a vacuum tube from the jacket can still be easily efiected because of the ready accessibility of the ring for opening and closing'thereof, and for the adjustment of any gaskets.

In the above description two posts only have been mentioned but more, -e. g. three, could be used if desired, so long as the space between the adjacent posts is large enough toaccomplish the desired purpose of permitting ready accessto or removal of the split ring; Likewise, the split ring may be made in more than two sections if desired.

While I have described particular embodiments of my invention for the purpose of illustration, it should be understood that various modifications and adaptations thereof may be made within the spirit of the invention as set forth inithe appended claims. v I

I claim: I

1. A water jacket assembly for an electron discharge device comprising a casing, a screw threaded clamping collar, a split ringpositioned coaxially with said collar and adapted to engage therewith and transmit clamping pressure from said collar to a portion of said discharge device, and a plurality of spaced posts extending from said casing and having means for engaging the screw threads of said clamping collar, the spacing between said posts being great enough to expose said split ring substantially entirely to view so that the seating thereof during the adjustment of said collar may be observed and ready access may be had directly to said ring.

2. A structure in accordance with claim 1 wherein said split ring is made of a plurality of separable sections and the spaces between said posts are great enough to permit the direct removal of said sections from said casing through said spaces.

3. A structure in accordance with claim 1 wherein said split ring comprises a plurality of sections hinged together. i i

4. A water jacket assembly for an electron discharge device having a shouldered anode, comprising a casing having a seat adapted to receive the shoulder of said anode, a screw threaded clamping collar for pressing said shoulder against said seat, a split ring positioned between said collar and said shoulder, and a plurality of spaced posts extending from said casing and having means for engaging the screw threads of said clamping collar, the spacing between said posts being great enough to expose said split ring and permit direct removal thereof from said casing through the space between said posts,
